Overview
The DTC124EE3TL is an NPN digital transistor from the ROHM DTC124E series, housed in a SOT-416 (EMT3) surface-mount package. It integrates biasing resistors with R1 and R2 both at 22 kΩ. Key electrical ratings include a supply voltage of 50 V, a maximum collector current of 100 mA, and a power dissipation of 150 mW. The device features a transition frequency of 250 MHz and a DC current gain of 56. Operating temperatures range from -55°C to +150°C.
Feature Summary
- Built-in biasing resistors enable inverter circuit configuration without external input resistors.
- Simplifies circuit design by requiring only on/off condition settings for operation.
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm the exact package type and taping specifications. Confirm RoHS compliance status and long-term availability plans directly with the manufacturer or authorized distributors before finalizing procurement decisions.
Selection Notes
Select this component for designs requiring integrated biasing to reduce external component count. Ensure the required collector current does not exceed 100 mA and that the operating voltage remains within the 50 V limit. Verify thermal management capabilities for the 150 mW power dissipation rating in the target application environment.
Part Context
This part belongs to the DTC124E series of NPN digital transistors. Complementary PNP types are available in the DTA124E series. The EMT3 package variant provides a compact footprint suitable for space-constrained surface-mount designs.
Replacement Considerations
DTA124EE3TL is a complementary PNP type within the same series. Other packages in the DTC124E family offer different form factors but share similar electrical characteristics.
